What Room Additions Involves
Room additions encompass many different types of construction that span everything from adding a single bedroom to major kitchen expansions. At their core, room additions involve expanding your home's current floor plan — either upward. This is different than remodeling, which works within the original layout.
These builds call for a collaborative approach that brings together architectural planning, building permits, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and cosmetic detailing. Because room additions require so many interconnected trades, working with a general contractor who can oversee every step is critical.
Room additions are a great fit for homeowners who want a dedicated space but want to keep their current property. They're also a popular choice for multigenerational households. Regardless of the scope, the work follows a clear set of stages that we have executed on hundreds of projects.
